Why do most body shops sand paint on car instead of chemical strip? best brand of chemical stripper?

The other question: I need to strip the hood of a car both inside and outside. Inside surface is very convoluted, and sanding wouldn't work since there is little flat surface. So I need a chemical stripper, but which type and brand: paste, liquid? Aircraft stripper? Kleen Strip? Jasco? Mostenbockers?


Does it have to be a stripper intended for cars? Can I use a stripper for wood or household?Why do most body shops sand paint on car instead of chemical strip? best brand of chemical stripper?
DO NOT sandblast it.! It will warp it so bad that it will be junk. The blasting creates so much heat that it warps it. You can use aircraft stripper, it works the best. Zip Strip will work also. You could chemical strip the top side yourself and have the bottom side baking soda / plastic media blasted (there are several different methods). Mask the edges of the panels to keep the stripper out of the cracks. If it gets in there you will never get it all out. When the car is done, the first time it is out in the sun, it will bake the stripper out of the cracks and ruin your new paint job. Chemical stripping is messy, caustic, etc. Having it blasted is expensive. Whatever method you use, do not sandblast it.


The only drawback to media blasting is it will not take rust off. Sand blasting works for door jambs, trunk openings, etc. but not large panels. If available in your area, there are companies that will dip the whole part in a big tank to strip / de-rust it. They can do complete car bodies.Why do most body shops sand paint on car instead of chemical strip? best brand of chemical stripper?
sanding removes what is needed to repaint or repair





chemical stripper removes everything down to bear metal like it was new dont need it


might be great on a metal chair or a table not great on a whole car might remove more than is needed





can use ny paint remover but type of paint or what its make for wil work best wouldnt use it on a car unless you starting from scratch down to metal and most case wil never need it done to paint a car





wet sand paint faster if your staying same color knock off the shine sand clean prime sand repaint or take off all the paint and primer have to rust coat sand prime sand prime sand paint sand paint sand clear coat sand clear coat cost you more to do samething another days works or more





could use it but why work so hard when might not have to





wet sand faster easier
Aircraft brand stripper is probably the most well known product.The residue must be washed off with water.When done stripping,use a garden hose to flush it thoroughly,then dry and wipe with an acid etch product to remove the flash rust.Body shops most often sand rather than chemical strip because it is rarely necessary to remove every trace of factory paint.That process is reserved for total panel restoration.
sometimes you will see a rough sand and they paint on that which will help the paint stick better. It can depend on the paint and where the paint is needed. Sand blasting can mess up rubber steals and what not, but with just straight sanding you can get in some places with out worring about wrecking anything else.
I agree with Steve C. Go the sandblasting method. If you have that many uneven surfaces, then liquid or gel paint stripper will never be removed 100% and it is very messy and toxic and expensive.


Actually you want to soda blast it, sand will destroy a lot of the metal and make it porous. Blasting of this type is popular with the fibreglass body of a corvette.EG:

This is your best bet to soda blast and then prime and paint the hood the color of choice.


Good luck........
Sand blasting followed by sanding or sanding alone will do the trick. Along with a good primer and some finish work, a professional looking job can be accomplished with a lot less hassle.


Chemical stripping is horribly messy, stinks, hard to clean off all of the residue and simply isn't necessary.
I suggest sandblasting it. A chemical stripper leaves a residue which is hard to get off.Paint will not stick to it for a long period of time before it starts cracking or in alot of cases it will seperate your paint as your applying it.then your back to square one.
autobody shops sand cars because of cost i suggest aircraft stripper if you use chemicals
SODA BLAST IT
